Abstract
Aims & objectives Prior to the popularization of magnetic intramedullary nails (MILNs), gradual deformity correction using external fixation was the norm in limb lengthening. Trauma literature has shown MILN via a suprapatellar approach (SP) to be associated with less knee pain than either an infrapatellar entry (IP) or external fixation. Yet, no research has investigated chronic knee pain and MILNs. We assessed differences in chronic knee pain following lengthening via an IP or SP approach with an MILN versus external fixation. Materials & methods We reviewed 147 limbs (55 MILN/IP, 22 MILN/SP, 71 external fixator) in 124 patients who underwent tibial lengthening with ≥12 months follow-up between February 2012 and July 2020. Knee pain was assessed pre- and postoperatively at 6 and 12 months, with the Lysholm Knee Scoring Scale (LKSS) and numeric pain scale (0-10). Differences in knee pain outcomes were compared across methods, with subgroup analysis of MILN/SP and MILN/IP. Results Mean LKSS was 96.3 for external fixation and 88.5 for MILN (P = .011). In the MILN subgroups, mean LKSS was 91.7 for IP and 85.3 for SP. The IP group reported a lesser mean pain score (0.6 versus 2.1) at 12 months. Bilateral nail recipients demonstrated no knee pain differences versus unilateral. At 12 months postoperative, external fixation had better knee outcomes. Conclusion Tibial lengthening with external fixation was associated with less chronic anterior knee pain and better functional outcomes than MILN overall. In terms of MILN approach, IP surpassed SP on subjective pain scores. Larger tibial lengthening and knee pain studies are warranted.

Abstract
A history of Clostridium difficile infection (CDI) before total knee arthroplasty (TKA) may be a marker for poor patient health and could be used to identify patients with higher risks for complications after TKA. We compared the frequency of 90-day postoperative CDI, complications, readmissions, and associated risk factors in (1) patients experiencing CDIs more than 6 months before TKA, (2) patients experiencing CDIs in the 6 months before TKA, and (3) patients without a history of CDI. We identified patients who underwent primary TKAs from 2010 to 2019 and had a history of CDI before TKA (n = 7,195) using a national, all-payer database. Patients were stratified into two groups: those with CDIs > 6 months before TKA (n = 6,027) and those experiencing CDIs ≤ 6 months before TKA (n = 1,168). These patients were compared with the remaining 1.4 million patients without a history of CDI before TKA. Chi-square and unadjusted odds ratios (ORs) with 95% confidence intervals (CI) were used to compare complication frequencies. Prior CDI during either timespan was associated with higher unadjusted odds for postoperative CDI (CDI > 6 months before TKA: OR 8.03 [95% CI 6.68-9.63]; p < 0.001; CDI ≤ 6 months before TKA: OR 59.05 [95% CI 49.66-70.21]; p < 0.001). Patients with a history of CDI before TKA were associated with higher unadjusted odds for 90-day complications and readmission compared with patients without a history of CDI before TKA. Other comorbidities and health metrics were not found to be associated with postoperative CDI (i.e., age, obesity, smoking, antibiotic use, etc.). CONCLUSION: CDI before TKA was associated with higher odds of postoperative CDI compared with patients without a history of CDI. CDI ≤ 6 months before TKA was associated with the highest odds for postoperative complications and readmissions. Providers should consider delaying TKA after CDI, if possible, to allow for patient recovery and eradication of infection.

Abstract
BACKGROUND A consumer-focused health care model not only allows unprecedented access to information, but equally warrants consideration of the appropriateness of providing accurate patient health information. Nurses play a large role in influencing patient satisfaction following total knee arthroplasty (TKA), but they come at a cost. A specific natural language artificial intelligence (AI) model, ChatGPT (Chat Generative Pre-trained Transformer), has accumulated over 100 million users within months of launching. As such, we aimed to compare: (1) orthopaedic surgeons' evaluation of the appropriateness of the answers to the most frequently asked patient questions after TKA; and (2) patients' comfort level in answering their postoperative questions by using answers provided by arthroplasty-trained nurses and ChatGPT. METHODS We prospectively created 60 questions based on the most commonly asked patient questions following TKA. There were 3 fellowship-trained surgeons who assessed the answers provided by arthroplasty-trained nurses and ChatGPT-4 to each of the questions. The surgeons graded each set of responses based on clinical judgment as: (1) "appropriate," (2) "inappropriate" if the response contained inappropriate information, or (3) "unreliable," if the responses provided inconsistent content. Patients' comfort level and trust in AI were assessed using Research Electronic Data Capture (REDCap) hosted at our local hospital. RESULTS The surgeons graded 44 out of 60 (73.3%) responses for the arthroplasty-trained nurses and 44 out of 60 (73.3%) for ChatGPT to be "appropriate." There were 4 responses graded "inappropriate" and one response graded "unreliable" provided by the nurses. For the ChatGPT response, there were 5 responses graded "inappropriate" and no responses graded "unreliable." There were 136 patients (53.8%) who were more comfortable with the answers provided by ChatGPT compared to 86 patients (34.0%) who preferred the answers from arthroplasty-trained nurses. Of the 253 patients, 233 (92.1%) were uncertain if they would trust AI to answer their postoperative questions. There were 127 patients (50.2%) who answered that if they knew the previous answer was provided by ChatGPT, their comfort level in trusting the answer would change. CONCLUSIONS One potential use of ChatGPT can be found in providing appropriate answers to patient questions after TKA. At our institution, cost expenditures can potentially be minimized while maintaining patient satisfaction. Inevitably, successful implementation is dependent on the ability to provide information that is credible and in accordance with the objectives of both physicians and patients. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Nonoperative treatment for clavicle fractures has historically been standard of care, but with a concomitant rise in recent operative fixation for displaced midshaft clavicle fractures (MCF), a re-evaluation of treatment modalities is necessary. The purpose of this study was to compare nonunion rates among operative and nonoperative treatment of closed displaced MCF. Specifically, we assessed the following between operative and nonoperative management: (1) 90-day to 1-year nonunion and malunion incidence; (2) 90-day medical complications; and (3) 90-day to 1-year total costs of care. METHODS An all-payer national database was retrospectively reviewed for closed displaced MCF from 2010 to 2020 (n = 173 188). Of these, patients undergoing operative fixation within 30 days of a displaced MCF were identified (n = 17 452). Nonoperative displaced MCF patients were matched with operative patients at a 3:1 ratio. Outcomes at 90 days and 1 year included: nonunion, total cost, and complications. RESULTS Closed displaced MCF with operative fixation resulted in significantly increased nonunion rates at 1 year compared with nonoperative treatment (3.97% vs 1.63%, odds ratio = 2.50 [2.26-2.77], P < .001). Kaplan-Meier survivorship and log-rank score demonstrated the same for a 1-year nonunion endpoint (P < .001). As expected, the operative cohort incurred higher median total costs of care at 90 days ($3255.00 vs $1024.00, P < .001) and 1 year ($1978.00 vs $4799.50, P < .001) compared with nonoperative treatment. CONCLUSION Our study found higher nonunion incidence after operative fixation of displaced MCF. These results may serve as a catalyst for future high-quality prospective studies comparing treatment options for closed displaced MCF.

Abstract
BACKGROUND There is increasing debate among orthopaedic surgeons over the temporal relationship between lumbar spinal fusion (LSF) and total hip arthroplasty (THA) for patients with hip-spine syndrome. Few large studies have directly compared the results of patients who undergo LSF prior to THA (LSF-THA) to those who undergo LSF after THA (THA-LSF). The current study matched THA patients with a prior LSF to patients who underwent LSF after THA to assess: 90-day and 1-year (1) medical/surgical complications; and (2) revisions. METHODS We queried a national, all-payer database to identify all patients undergoing THA between 2010 and 2018 (n = 716,084). The LSF-THA patients and THA-LSF patients were then matched 1:1 on age, sex, Charleson Comorbidity Index, and obesity. Medical/surgical complications and revisions at 90 days and 1 year were recorded. Categorical and continuous variables were analysed utilising t-tests and chi-square, respectively. RESULTS LSF-THA patients experienced significantly more postoperative dislocations at 90 days and 1 year compared to THA-LSF patients (p = 0.048 and p < 0.001). There were a similar number of revisions performed for LSF-THA and THA-LSF patients at both 90 days and 1 year (p = 0.183 and p = 0.426). Furthermore, at 1 year, LSF-THA patients experienced more pneumonia (p = 0.005) and joint infection (p = 0.020). CONCLUSIONS Prior LSF has been demonstrated to increase the risk of postoperative dislocation in patients undergoing THA. The results of the present study demonstrate increased dislocations with LSF-THA compared to THA-LSF. For "hip spine syndrome" patients requiring both LSF and THA, it may be more beneficial to undergo THA prior to LSF. Arthroplasty surgeons may wish to collaborate with spinal surgeons to ensure optimal outcomes for this group of patients.

Abstract
PURPOSE Carpal tunnel syndrome is the most common compressive neuropathy. There is limited evidence to support endoscopic compared to open carpal tunnel release according to the 2016 American Academy of Orthopaedic Surgeons Clinical Practice Guideline on carpal tunnel syndrome. The purpose of the present study was to assess differences between the two procedures by comparing 30- and 90-day complications and mean hospital costs in a large patient population. METHODS Using the national Mariner15 Database by PearlDiver Technologies, we retrospectively studied 27,192 carpal tunnel syndrome patients who received carpal tunnel release using an endoscopic or open surgical approach from 2010 to 2019. Patients who met the inclusion criteria were grouped and case-matched at a 1:1 ratio through the corresponding International Classification of Diseases codes (n = 13,596) and assessed for 30- and 90-day complications such as median nerve injury, superficial palmar arch injury, and revision carpal tunnel release surgery. Univariate analysis was used to compare outcomes and a multivariate regression was performed to identify risk factors associated with each outcome. RESULTS Endoscopic carpal tunnel release was associated with a higher rate of median nerve injury than open release at 30 days (0.3% vs. 0.1% odds ratio, 2.21; 95% confidence interval, 1.29-3.81; p < 0.05) and 90 days (0.4% vs. 0.3%; odds ratio, 1.77; 95% confidence interval, 1.16-2.70; p < 0.05). Endoscopic release was also associated with a higher rate of superficial palmar arch injury (0.1% vs. 0%; odds ratio, 25.02; 95% confidence interval, 1.48-423.0; p < 0.05). CONCLUSIONS In the present study, risk of median nerve injury and vascular injury was higher after endoscopic than open carpal tunnel release. At 90 days, all-cause revision rates were similar between techniques. Surgeons should understand these differences, to optimize surgical decision-making. LEVEL OF EVIDENCE Therapeutic, IIIa.

Abstract
Skin closure for total knee arthroplasty (TKA) typically focuses on promoting optimal healing, while preventing wound complications and infection, allowing for functionality and immediate ambulation, and providing for excellent cosmesis. In this systematic review and meta-analysis of the literature, we will focus on closure of the skin. Specifically, we assessed: (1) wound complication risk of different techniques and (2) closing time of different sutures/techniques. There were 20 reports on infection risk and closing time. Meta-analyses focused on the qualifying studies for closing time and wound complication risk reports were also performed. These studies (378 patients) demonstrated overall lower wound complication risks with the use of barbed compared with traditional sutures (3% vs. 6%, p < 0.05). The subsequent meta-analysis included 749 patients demonstrating overall significant closing time reductions of a mean of 7 minutes with the use of barbed sutures (p < 0.05). Therefore, multiple recent reports suggest superior outcomes and faster results when using barbed sutures for TKA skin closure.

Abstract
Over 25% of patients with rheumatoid arthritis (RA) are expected to undergo a joint replacement during their lifetime. Current practice guidelines recommend withholding biologic therapy 1 week prior to total hip arthroplasty, given its immunosuppressive effects. Most patients are on a regimen including biologic and nonbiologic therapy; however, the individual influences of these therapies are not well understood in the setting of total knee arthroplasty (TKA). Therefore, we sought to compare biologic, nonbiologic, and recipients of both types of therapy in patients with RA undergoing TKA. We specifically assessed (1) medical complications at 90 days; (2) surgical complications up to 1 year; and (3) independent risk factors for prosthetic joint infections (PJIs).A retrospective review was conducted using a national, all-payer database for patients undergoing primary TKA from January 2010 to April 2020 (n = 1.97 million). Patients diagnosed with RA were then separated into at least 1-year users of biologic (n = 3,092), nonbiologic (28,299), or dual (n = 10,949) therapy. Bivariate analyses were utilized to assess for 90-day medical and up to 1-year surgical outcomes. Additionally, multivariate regression models were utilized to assess for independent risk factors.The incidence and odds ratio for medical/surgical outcomes were equivocal among the biologic, nonbiologic, and recipients receiving both types of therapy (p > 0.061). No differences were observed between the type of therapy as additional risk factors for infection (p > 0.505). However, glucocorticoids at 90 days and alcohol abuse, diabetes mellitus, obesity, as well as tobacco use were identified as additional risk factors for PJI(p < 0.036).No appreciable differences in medical or surgical outcomes were associated with the independent use of biologic, nonbiologic, or recipients of both types of therapy in patients with RA. Additionally, alcohol abuse, diabetes mellitus, glucocorticoids, obesity, and tobacco use conferred an increased risk of PJI. These results can serve as an adjunct to current practice guidelines.

Abstract
INTRODUCTION Morbid obesity is a known risk-factor for increased complications following total hip arthroplasty (THA). Thus, many orthopaedic surgeons recommend bariatric surgery (BS). However, there is no consensus on the type (commonly either a Roux-en-Y gastric bypass [RYGB] or sleeve gastrectomy [SG]) and timing of BS prior to THA. Therefore, the purpose of this study is to compare BS recipients prior to THA to assess differences in 90-day to 2-year medical/surgical complications as well as revisions for: (1) type of BS (RYGB and SG); and (2) timing of BS. Additionally, we aim to assess risk factors for postoperative prosthetic joint infections (PJIs), dislocations, and revisions. METHODS We queried a national, all-payer database to identify patients undergoing primary THA from January 2010 to October 2020 (n = 715,100). Patients were then divided into 6 cohorts: 2 cohorts without history of BS (body mass index [BMI] kg/m2 20-35 [n = 59,995]) and BMI > 40 [n = 36,799]); 2 cohorts with previous RYGB (n = 1278) or SG (n = 1051); and 2 cohorts that underwent BS either 6-12 months (n = 412) and >12 months (n = 1655) prior to the THA. Bivariate chi-square analyses of medical and surgical outcomes at 90 days-2 years were conducted. Multivariate logistic regressions identified independent risk factors for PJIs, dislocations, and revisions. RESULTS At 90 days-2 years, no differences in postoperative medical/surgical complications or revisions were seen among timing or type of BS. The BMI > 40 kg/m2 cohort had the highest complication profile among all other cohorts. Timing and type of BS has similar odds of PJIs, dislocations, and revisions. CONCLUSIONS Patients undergoing RYGB or SG 6-12 months and >1 year prior to THA showed similar complications profiles. These results suggest, bariatric patients do not need to wait 1 year before undergoing a THA.

Abstract
Introduction Arthrofibrosis occurs in up to 10% of patients who undergo total knee arthroplasty (TKA). For cases that are not amenable to manipulation under anesthesia (MUA), there is little consensus on how many components should be revised. We compared outcomes of polyethylene exchanges, when doing lysis of adhesions (LOA) versus full component revision. Specifically, we assessed: (1) re-operation rates at one and two years; (2) rates of surgical complications at one year; and (3) associated risk factors for requiring a LOA. Methods A database queried all patients who underwent revision TKA for arthrofibrosis. A total of 2410 patients were identified, 1120 (46.5%) of which underwent all-component knee revision, while the remaining 1290 (53.5%) underwent polyethylene spacer revision. Multivariate logistic regressions assessed re-operation rates and risk factors for requiring LOA. Results The incidence and odds of re-operation within one year following polyethylene exchange was not significantly different than full component revision (10.9 versus 12.9%, odds ratio (OR) 0.83, 95% confidence interval (CI) [0.64-1.06], p = 0.145). However, the adjusted models for re-operation within one- and two-years following LOA in the form of polyethylene exchange revision was significantly higher than the full component revision cohort (OR 1.52 CI [1.07-2.17], p = 0.022 and OR 1.44 CI [1.06-1.97] p = 0.022). Risk factors associated with the need for lysis of adhesions included age less than 60 years, depression, fibromyalgia, and anxiety. Conclusions Full component revision TKA for arthrofibrosis was associated with lower two-year re-operation rate than polyethylene exchange. Risk factors for LOA include younger age and fibromyalgia.

Abstract
INTRODUCTION The pleiotropic effects of statins extend beyond managing cardiovascular health and are suggested to modulate Staphylococcus aureus biofilm formation with prosthetic joint infection (PJI) reduction. However, a large analysis of statin use prior to total joint arthroplasty (TJA) to determine infection and revision risk is lacking. We specifically evaluated: 90-day to two-year (1) prosthetic joint infection (PJIs); (2) revisions; and (3) respective risk factors. MATERIALS AND METHODS We queried a national, all-payer database for patients undergoing either TKA or THA between 2010-2020. Chronic statin exposure was defined as >3 prescriptions filled within one-year prior to TJA (statin users). A control cohort of patients undergoing TJA without history of statin use prior was identified (statin naïve). Cohorts were matched 1:1 based on demographics and comorbidities (TKA: n=579,136; THA: n=202,092). Multivariate logistic regression was performed to evaluate risk factors for PJIs and revisions. RESULTS Among TKA recipients, statin users had lower incidence of PJIs at one year (0.36 vs. 0.39%) to two years (0.45 vs. 0.49%) compared to the statin naïve (all, p≤0.007). Similarly, statin users had lower incidence of one- to two-year revisions (all, p≤0.048). Among THA recipients, statin users had lower incidence of PJIs at 90 days (0.37 vs. 0.45%) to two years (2% vs. 2.14%) (all, p<0.001). Similar trends were observed for 90-day to two-year revisions (all, p≤0.022). Statin use was independently associated with decreased odds of PJIs and revisions by one year. CONCLUSIONS Statin use is associated with a reduced risk of PJIs and revisions from one to two years following TJA. It may be worthwhile to ensure patients take statin therapy if indicated for previously established cardiovascular guidelines.

Abstract
BACKGROUND Much of the literature on osteonecrosis has traditionally focused on the hip, which remains the most common site for this disease. The shoulder and the knee are the second most frequently affected sites (both approximately 10% of the incidence). There are a variety of techniques for managing this disease, and it is important to optimize this for our patients. This review aimed to compare the results of core decompression (CD) vs. nonoperative modalities for the treatment of osteonecrosis of the humeral head, including (1) success rate defined as lack of progression to further procedures (shoulder arthroplasty) and no need for further intervention; (2) clinical results (patient-reported pain and functional scores); and (3) radiological outcomes. METHODS We queried PubMed and found 15 reports that fit the inclusion criteria for studies concerning the use of CD as well as studies discussing nonoperative treatment for stage I-III osteonecrotic lesions of the shoulder. A total of 9 studies encompassed 291 shoulders that underwent CD analyzed at a mean follow-up of 8.1 years (range, 67 months-12 years), and 6 studies examined 359 shoulders that underwent nonoperative management at a mean follow-up of 8.1 years (range, 35 months-10 years). Outcomes of CD and nonoperative management included success rate, number of shoulders requiring shoulder arthroplasty, and evaluation of several normalized patient-reported outcomes. We also assessed radiographic progression (pre- to postcollapse or further collapse progression). RESULTS The mean success rate of CD for avoiding further procedures was 76.6% (226 of 291 shoulders) in stage I through stage III. Stage III shoulders avoided shoulder arthroplasty in 63% (27 of 43 shoulders). Nonoperative management resulted in a success rate of 13%, P < .001. In the CD studies, 7 of 9 showed improvements in clinical outcome measurements compared with 1 of 6 of the nonoperative studies. Radiographically, there was less progression in the CD group (39 of 191 shoulders [24.2%]) vs. the nonoperative group (39 of 74 shoulders [52.3%]) (P < .001). CONCLUSIONS Given the high success rate and positive clinical outcomes reported, CD is an effective method for management, especially when compared with nonoperative treatment methods for stage I-III osteonecrosis of the humeral head. The authors believe that it should be used as treatment to avoid arthroplasty in patients who have osteonecrosis of the humeral head.

Abstract
BACKGROUND Trigger finger may be treated with open surgical release. Local corticosteroid injections have also demonstrated success. Studies suggest recipients of flexor sheath corticosteroid up to 90-days prior to open surgery are at increased risk of post-operative infection. However, the possible link between large joints corticosteroid prior to trigger finger release remains unexplored. Therefore, this study aimed to provide complication risks for trigger finger release recipients after large joint corticosteroid. METHODS We reviewed a national, all-payer database and examined patients who did not receive and did receive corticosteroid two, four, or six weeks prior to trigger finger release. Primary outcomes assessed were 90-day risk for antibiotics, infection, and irrigations and debridement. Multivariate logistic analyses compared cohorts using odds ratios with 95% confidence intervals. RESULTS No trends were found regarding antibiotic requirements, infection, as well irrigations and debridement within 90-days for recipients of corticosteroid into large joints two, four, or six weeks prior to open trigger finger release. Elixhauser Comorbidity Index, alcohol abuse, diabetes mellitus, and tobacco use were identified as independent risks for requiring antibiotics as well as irrigations and debridement (all Odds Ratios > 1.06, all p ≤ 0.048). CONCLUSIONS Patients who underwent trigger finger release after receiving a corticosteroid into a large joint two, four, or six weeks prior has no association with 90-day antibiotics, infection, or irrigations and debridement. While the comfort levels for individual surgeons vary, optimizing these comorbidities prior to surgery is an important goal discussed with patients to lower risks for infections.

Abstract
The purpose of this study is to examine patients undergoing primary total knee arthroplasty (TKA) with and without prior history of statin use. We specifically evaluated (1) 90-day to 2-year periprosthetic fractures, (2) revisions, and (3) respective risk factors. We queried a national, all-payer database for patients undergoing primary TKA between 2010 and 2020. Chronic statin exposure was then identified and defined as more than three prescriptions filled within 1 year prior to TKA (statin users). A control cohort of patients undergoing TKA without the prior history of statin use was then created (statin naïve). Cohorts were matched 1:1 based on age range, Charlson Comorbidity Index, sex, diabetes, obesity, and tobacco use, yielding 579,136 patients. Multivariate logistic regression was performed to evaluate the risk factors for periprosthetic fractures and revisions, adjusted for demographics and comorbidities. Statin users had a lower incidence of periprosthetic fractures from 90 days to 2 years compared with the statin naïve (p < 0.001). Similarly, statin users had a lower incidence of revisions at 90 days to 2 years (p < 0.001). Using the statin-naïve cohort as a reference, statin use was independently associated with decreased odds of periprosthetic fractures and revisions. Statin use was associated with a reduced risk of periprosthetic fractures and revisions. These results may mitigate postoperative risks though statin therapy is currently not recommended for fracture-related benefits alone.

Abstract
INTRODUCTION Over ⅓ of the population in the United State is obese (body mass index [BMI] >30 kg/m2), with an increasing proportion being morbidly obese (BMI >40 kg/m2). As the obesity rate climbs, an increasing number have entered the super-obese category (BMI >50 kg/m2), theoretically increasing risk for complications after total hip arthroplasty (THA). This study compared complications in non-obese, obese, morbidly obese, and super-obese patients undergoing THA. We specifically assessed: (1) 1- and 2-year peri-prosthetic joint infection (PJI) rates; (2) complication rates; as well as (3) 1- and 2-year revision rates. METHODS A database review identified patients undergoing primary THA from 01 January 2010 to 31 December 2019. Patients were stratified based on the presence of International Classification of Diseases, 9th and 10th revision diagnosis codes of non-obese (BMI <30 kg/m2) (n = 8680), obese (BMI <40 kg/m2) (n = 12,443), morbidly obese (BMI <50 kg/m2) (n = 5250), and super-obese (BMI >50 kg/m2) (n = 814) prior to THA. Complication rates at 90 days, 1 year, and 2 years were compared across groups. RESULTS At all time points, super-obese patients were associated with higher rates of PJI, even when compared to morbidly obese patients. Complications such as sepsis, venous thrombo-embolism, and revision surgeries were found in higher numbers in super-obese as well as morbidly obese patients, compared to obese and non-obese patients. CONCLUSIONS This study provides large-scale analyses demonstrating the association between super-obese and morbidly obese patients and higher infection rates, as well as complications, following THA. Importantly, the association of PJI is highest among super-obese patients, even when compared to morbidly obese patients. Attaining a BMI <40 kg/m2 prior to surgery may be an important goal discussed with patients to lower the chance of postoperative infections.

Abstract
Cartilage restoration procedures are effective for articular defects of the knee. However, studies suggest decreased clinical improvements after total knee arthroplasty (TKA). The purpose of this study was to compare patients who had a prior cartilage restoration undergoing TKA with patients who had TKA without a prior cartilage restoration procedure. We specifically assessed (1) 90-day and 1-year medical/surgical complications; (2) 90-day and 1-year revision rates; and (3) 90-day costs. A search using a national, all-payer database examined matched cohorts of patients who underwent cartilage restoration procedures prior to TKA (n=22,072) and controls who did not (n=220,364) between January 1, 2010, and April 30, 2020. Cartilage restoration procedures included autologous chondrocyte implantation, microfracture, osteochondral autograft transfer system operations, or open and arthroscopic osteochondral allograft transplantation. Outcomes studied included lengths of stay, 30-day readmission rates, 90-day costs, and medical and surgical complications to include 90-day and 1-year prosthetic joint infections, pathologic fractures, dislocations, knee manipulations, and revisions. Comparable rates of 90-day and 1-year medical and surgical complications were found for TKAs after cartilage restoration. Additionally, 90-day and 1-year revision surgery rates were similar. These patients were also found to have 90-day costs almost identical to those of patients who did not have cartilage restoration. This large analysis of patients with cartilage restoration procedures prior to TKA demonstrated that the complication rates may be similar to those of patients who do not have these operations before TKA. These findings provide valuable information to surgeons and patients when deciding to proceed with TKA after cartilage restoration. [Orthopedics. 2023;46(4):250-255.].

Abstract
INTRODUCTION Incidence of bacteremia following screening colonoscopy is low, but risk of hematogenous spread causing prosthetic joint infection (PJI) may exist in total knee arthroplasty (TKA) patients. In multivariate analyses, we examined PJI risk among three TKA cohorts: (1) colonoscopy recipients given antibiotic prophylaxis; (2) colonoscopy recipients not given antibiotic prophylaxis; and (3) no colonoscopy. We assessed: 90-day to one-year (A) PJI risk, and (B) risk factors for post-colonoscopy PJI. METHODS We queried a national, all-payer database for primary TKA recipients from 2010 to 2020. Patients who had colonoscopies and who did (n=2,558) or did not have antibiotic prophylaxis (n=20,000) were identified. These were compared those who did not undergo colonoscopy (n=20,000). The 20,000 patients were randomly selected to mitigate type 1 errors. Multivariate regressions compared PJI risk factors, such as alcohol abuse (AA), rheumatoid arthritis (RA), and diabetes. RESULTS Both colonoscopy cohorts had no increased PJI risk compared to non-colonoscopy (odds ratio (OR)<2.20, P≥0.064). Alcohol abuse, diabetes, and RA were found to be risk factors further enhancing likelihood of PJI for TKA patients not receiving antibiotics undergoing colonoscopies (OR>1.35, P≤0.044). CONCLUSION Overall, antibiotic prophylaxis does not decrease PJI risk following colonoscopy TKA recipients. After adjusting for known risk factors, both colonoscopy cohorts demonstrated similar PJI risks compared to the non-colonoscopy cohort. However, AA, diabetes, and RA were associated with further increased PJI risk for TKA patients undergoing colonoscopies compared to those who did not. Therefore, if undergoing colonoscopy after TKA, our findings suggest that most patients do not need to have antibiotics except for these high-risk patients.

Abstract
BACKGROUND The number of liver transplant recipients (LTR) is worldwide increasing and, as the survival is improving as well, there is an increasing number of patients needing total hip arthroplasty (THA). There might be increased risks for this specific group of patients and due to their comorbidities costs might be higher too. Using a big national database outcome and cost of THA should be compared between liver transplant recipients and the general population. METHODS The study was performed using a collection of Medicare, Medicaid, and private insurance claims. Length of stay (LOS), 30-day readmissions, complications rates up to 5 years, and 90-day total cost of care between liver transplant recipients and matched non-transplant patients should be compared. All primary THAs from 2010 to 2019 were identified. 513 patients with a liver transplant before their THA were matched to 10,759 patients without a history of solid organ transplant at a 1:20 ratio based on age, sex, Charlson Comorbidity Index, obesity, and diabetes status. RESULTS LTR had a longer average LOS (4.2 vs. 3.4 days, p < 0.001). There was no difference in the thirty-day readmissions (5.7% vs. 4.1%, p = 0.117) and 90-day dislocation rates (2.9% vs. 2.4%, p = 0.600). Total costs in the first ninety days after THA were not different between the LTR and controls (p = 0.756). CONCLUSIONS These findings suggest that complications and costs are no major point of concern in patients with liver transplant that are operated with THA.

Abstract
Antibiotic prophylaxis before an invasive dental procedure (IDP) for patients with preexisting knee implants has been suggested, but its use has yet to reach consensus. Therefore, we sought to examine antibiotic prophylaxis before an IDP for patients who had undergone a total knee arthroplasty (TKA). We specifically assessed 90-day to 1-year (1) periprosthetic joint infection (PJI) and (2) revision. We queried a national, all-payer database for patients undergoing primary TKA between 2010 and 2020 (n=1,952,917). We identified IDP, as defined by any procedure that involves gingival manipulation, and stratified according to antibiotic prophylaxis. A control cohort of TKA recipients without subsequent IDP was then established. All 3 cohorts were matched according to demographic and health metrics (n=496). Chi-square testing generated the odds ratio (OR) with 95% CI for postoperative PJI and revision. The odds for PJI and revision at all time points were statistically similar between antibiotic prophylaxis and no antibiotic prophylaxis (PJI: OR, 0.62; 95% CI, 0.11-4.00; P≥.479; revision: OR, ≥0.33; 95% CI, 0.03-4.00; P≥.248). Additionally, both IDP cohorts and the control cohort had similar rates of postoperative PJI (P≥.367) and revision (P≥.173) at all time points. Antibiotic prophylaxis before an IDP for TKA recipients did not decrease the risk of PJI or revision up to 1 year after the index procedure. These results support the trend by dentists and orthopedic surgeons to refrain from antibiotic prophylaxis. However, it likely has utility in patients at high risk, as suggested by current guidelines. [Orthopedics. 2023;46(2):76-81.].

Abstract
Clubfoot management has advanced in the 21st century with increases in formal training, practitioner experience, and improved casting/bracing constructs. The Ponseti method is the gold standard, yet variations in application persist. This survey aims to identify current treatment practices among clubfoot practitioners within the Pediatric Orthopaedic Society of North America (POSNA). A 23-question online survey of members was conducted between June and August 2021. Eighty-nine respondents self-identified as clubfoot providers. Of these, 93.1% had an MD degree, 23.6% possessed >30 years’ experience, and the majority (65.6%) worked in a teaching hospital associated with a medical school. Most responders (92.0%) were pediatric fellowship trained. A total of 51.7% had participated in a clubfoot training course. More than half (57.5%) noted changes to clubfoot management practices throughout their training. A majority used between four and seven (88.7%) long leg casts (98.4%), changed at seven-day intervals (93.4%). Plaster (69.4%) was most commonly used. The most common bracing device was Mitchell–Ponseti (72.9%). A mean 84.8% of clubfeet required tenotomy. The most common anesthetic agent was numbing gel (43.0%). Tenotomies mostly occurred in patients aged <6 months (63.1%). Tenotomy locations were operating room (46.5%), clinic (45.4%) and procedure room (8.1%). Cast removal was primarily performed with saws (54.7%). The mean incidence of observed cast burns was 5.5%. Most providers did not use a device to prevent cast burns (76.6%). Reported cast complications included slippage (85.9%), skin irritation (75.8%), and saw-related injuries (35.9%). Clubfoot management variations exist in orthotics, tenotomy indications and practices, and cast material. Casting complications continue to be a problem. Further studies are warranted to determine if certain practices predispose patients to specific complications.

Abstract
Intra-articular injections prior to total hip arthroplasty (THA) have been associated with postoperative infections. The purpose of this study was to determine whether a temporal relationship exists between hip injections prior to THA and infection. Specifically, we asked (1) Do patients who receive hip injections within 3 months of THA have a higher incidence of prosthetic joint infections (PJIs) or surgical site infections (SSIs)? and (2) Do these patients incur higher 90-day costs? Patients with hip injections prior to THA were identified using a national database from 2010 to 2019. Three laterality-specific groups (injection 0 to 3 months, 3 to 6 months, and 6 to 12 months prior to THA)were compared with a matched cohort without prior injection (n=277,841). Primary outcomes included PJIs, SSIs, and costs. Patients who had injections within 3 months of THA had a higher incidence of PJIs at 90 days (5.1% vs 1.6%, P<.01) and 1 year (6.8% vs 2.1%, P<.01), when compared with the matched cohort. They also had a higher incidence of SSIs at 90 days (2.8% vs 1.2%, P<.01) and 1 year (3.7% vs 1.7%, P<.01). Mean costs were 13.7% higher in this injection cohort. Patients who had injections between 3 and 6 months prior to THA had higher incidence and odds of postoperative PJIs at 90 days (2.6% vs 1.6%, P<.04), whereas those with injections beyond 6 months had no differences in PJIs (P≥.46). Patients who receive hip injections within 3 months of undergoing primary THA are at increased risk for postoperative PJIs, SSIs, and higher costs. This study reaffirms guidelines for when to perform THAs in these populations. [Orthopedics. 2023;46(1):19-26.].

Abstract
BACKGROUND Magnetic intramedullary lengthening nails (MILNs) have gained popularity in recent years for the treatment of limb-lengthening discrepancies. We sought to catalog mechanical failures and their prevention and management in a large, single-institution series. We specifically assessed the rate of mechanical failures, the types of failures observed, and management strategies. METHODS We retrospectively reviewed 377 patients (420 limbs) who underwent limb lengthening with early (P1) or later (P2) MILN iterations with ≥12-month follow-up. Mechanical failure was defined as mechanical breakage of the instrumentation or nail and/or failure of the internal lengthening mechanism. Failure assessment was arranged by lengthening phases and was sorted with a complication classification system. All lengthening and alignment parameters were assessed radiographically. RESULTS Mechanical failure was observed in 40 nails (9.5%), most of which (63%) were corrected with an additional surgical procedure. The mechanical failure rate was 11.3% in P1 nails and 9% in P2 nails. Two nails failed the intraoperative distraction test, and 1 nail was found to have a broken washer during the insertion phase. Sixteen nails had mechanical failures in the lengthening phase. Some nails (8 of 16) required nail replacement surgery. Thirteen nails failed during the consolidation phase; 7 of these cases were managed by replacement with either a functional MILN or a conventional intramedullary nail. Eight failures happened during the extraction phase and were managed intraoperatively. CONCLUSIONS A 9.5% overall rate of mechanical failure of MILNs was observed in this large series. Resolution was achieved with an additional surgery in most cases. Nail distraction and weight-bearing compliance should be closely monitored during the lengthening and consolidation phases. Nail removal can be difficult and requires a careful study of radiographs for locking-screw bone overgrowth and backup removal equipment. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
BACKGROUND Few studies investigate the influence of inflammatory bowel disease (IBD) on complications following total knee arthroplasty (TKA). Therefore, we compared complications and readmissions frequencies after TKA in patients with Crohn's disease (CD) and ulcerative colitis (UC) to patients without IBD. METHODS A large administrative claims database was used to identify patients who underwent primary TKAs from 2010 to 2019 and had a diagnosis of IBD before TKA. Patients were stratified into two groups: those with CD (n = 8,369) and those with UC (n = 11,347). These patients were compared a control of 1.3 million patients without an IBD diagnosis. Chi-square and unadjusted odds ratios (OR) with 95% confidence intervals (CI) were used to compare complication frequencies. Multivariable logistic regression was used to evaluate independent risk factors for 90-day complications. RESULTS Compared to patients without IBD, patients with IBD were associated with higher unadjusted 90-day odds for Clostridium difficile infection (CDI) (CD: OR 2.81 [95% CI 2.17 to 3.63]; p < 0.001; UC: OR 3.01 [95% CI 2.43 to 3.72]; p < 0.001) and two-year periprosthetic joint infection (CD: OR 1.34 [95% CI 1.18 to 1.52]; p < 0.001; UC: OR 1.26 [95% CI 1.13 to 1.41]; p < 0.001). After controlling for risk factors like obesity, tobacco use, and diabetes, both types of IBD were associated with higher 90-day odds for CDI and PJI (p < 0.001 for all). CONCLUSION IBD is associated with higher 90-day postoperative CDI and PJI compared with patients without IBD. Providers should consider discussing these risks with patients who have a diagnosis of IBD.

Abstract
BACKGROUND Prior literature has associated preoperative corticosteroid shoulder injection (CSI) with infection following shoulder surgery. A recent study found an equally elevated risk of total knee arthroplasty infection with preoperative injection of either CSI or hyaluronic acid. The implication is that violation of a joint prior to surgery, even in the absence of corticosteroid, may pose an elevated risk of infection following orthopedic surgery. The aim of the present study was to determine whether violation of the shoulder joint for magnetic resonance arthrogram (MRA) poses an elevated risk of infection following shoulder arthroscopy, and to compare this risk to that introduced by preoperative CSI. METHODS A national, all-payer database was queried to identify patients undergoing shoulder arthroscopy between January 2015 and October 2020. Patients were stratified into the following groups: (1) no CSI or MRA within 6 months of surgery (n = 5000), (2) CSI within 2 weeks of surgery (n = 1055), (3) CSI between 2 and 4 weeks prior to surgery (n = 2575), (4) MRA within 2 weeks of surgery (n = 414), and (5) MRA between 2 and 4 weeks prior to surgery (n = 1138). Postoperative infection (septic shoulder or surgical site infection) was analyzed at 90 days, 1 year, and 2 years, postoperatively. Multivariable logistic regression analysis controlled for differences among groups. RESULTS MRA within 2 weeks prior to shoulder surgery was associated with an increased risk of infection at 1 year (odds ratio [OR], 2.17; P = .007), while MRA 2-4 weeks preceding surgery was not associated with an increased risk of postoperative infection at any time point. By comparison, CSI within 2 weeks prior to surgery was associated with an increased risk of postoperative infection at 90 days (OR, 1.72; P = .022), 1 year (OR, 1.65; P = .005), and 2 years (OR, 1.63; P = .002) following surgery. Similarly, CSI 2-4 weeks prior to surgery was associated with an increased risk of postoperative infection at 90 days (OR, 1.83; P < .001), 1 year (OR, 1.62; P < .001), and 2 years (OR, 1.79; P < .001). CONCLUSION Preoperative CSI within 4 weeks of shoulder arthroscopy elevates the risk of postoperative infection. Needle arthrotomy for shoulder MRA elevates the risk of infection in a more limited fashion. Avoidance of MRA within 2 weeks of shoulder arthroscopy may mitigate postoperative infection risk. Additionally, the association between preoperative CSI and postoperative infection may be more attributed to medication profile than to needle arthrotomy.

Abstract
BACKGROUND Use of "orthobiologics" continues to expand for patients who have knee osteoarthritis (OA). We sought to perform a systemic review of biologic therapies relative to comparative groups, including the following: (1) platelet-rich plasma (PRP); (2) bone marrow-derived mesenchymal stem cells (BMSCs); (3) adipose-derived mesenchymal stem cells (ADSCs); and (4) amniotic-derived mesenchymal stem cells (AMSCs). We assessed the following: (1) study methodologies; (2) cell preparations and formulations; (3) patient-reported outcome scores (PROMs); and (4) structural changes. METHODS PubMed, Cochrane Library, and Embase databases were queried (2013-2021) to conduct a systematic review of biologic therapies for knee OA, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eighty-two studies were included: PRP (51); BMSC (15); ADSC (11); and AMSC (5). Study evaluations were made using the Modified Coleman Methodology Score. PROMs included the Western Ontario and McMaster Universities Arthritis Index and the Visual Analog Scale. Structural change evaluations included ultrasounds, radiographs, or magnetic resonance imaging. RESULTS PRP comprised a majority of the studies (n = 51), most with "fair" to "good" Modified Coleman Methodology Score. Studies had variable cell preparations and formulations, with comparison study results leading to inconsistent PROMs, and structural changes. A limited number of studies were included for BMSC, ADSC, and AMSC, all with similar findings to PRP. CONCLUSION Available literature evaluating "orthobiologics" for knee OA remain nonsuperior to comparison cohorts. Higher level studies with larger sample sizes and improved methodologies are warranted to suggest differences. Despite a growth of "orthobiologics" in clinics, this updated systematic review highlights the uncertain efficacy for use in knee OA.

Abstract
UNLABELLED Osteosarcopenia is a common condition among elderly and postmenopausal female patients. Site-specific bone mineral density is more predictive of bone-related complications. Few studies have investigated muscle-bone associations. Our results demonstrated that in women, significant positive associations between paraspinal muscles FCSA and vBMD exist at different lumbosacral levels. These regional differences should be considered when interpreting bone-muscle associations in the lumbar spine. INTRODUCTION There is increasing evidence between bone and muscle volume associations. Previous studies have demonstrated comorbidity between osteoporosis and sarcopenia. Recent studies showed that sarcopenic subjects had a fourfold higher risk of concomitant osteoporosis compared to non-sarcopenic individuals. Although site-specific bone mineral density (BMD) assessments were reported to be more predictive of bone-related complications after spinal fusions than BMD assessments in general, there are few studies that have investigated level-specific bone-muscle interactions. The aim of this study is to investigate the associations between muscle functional cross-sectional area (FCSA) on magnetic resonance imaging (MRI) and site-specific quantitative computed tomography (QCT) volumetric bone mineral density (vBMD) in the lumbosacral region among spine surgery patients. METHODS We retrospectively reviewed a prospective institutional database of posterior lumbar fusion patients. Patients with available MRI undergoing posterior lumbar fusion were included. Muscle measurements and FCSA were conducted and calculated utilizing a manual segmentation and custom-written program at the superior endplate of the L3-L5 vertebrae level. vBMD measurements were performed and calculated utilizing a QCT pro software at L1-L2 levels and bilateral sacral ala. We stratified by sex for all analyses. RESULTS A total of 105 patients (mean age 61.5 years and 52.4% females) were included. We found that female patients had statistically significant lower muscle FCSA than male patients. After adjusting for age and body mass index (BMI), there were statistically significant positive associations between L1-L2 and S1 vBMD with L3 psoas FCSA as well as sacral ala vBMD with L3 posterior paraspinal and L5 psoas FCSA. These associations were not found in males. CONCLUSIONS Our results demonstrated that in women, significant positive associations between the psoas and posterior paraspinal muscle FCSA and vBMD exist in different lumbosacral levels, which are independent of age and BMI. These regional differences should be considered when interpreting bone and muscle associations in the lumbar spine.

Abstract
Hyaluronic acid (HA) and corticosteroid (CS) injections are utilized in symptom management for patients with osteoarthritis. However, contamination of the joint may increase the risk of infection following total knee arthroplasty (TKA). Therefore, the purpose of this study was to examine 90-day surgical site infection (SSI) and manipulation under anesthesia (MUA) as well as up to 2-year prosthetic joint infection (PJI) in intra-articular knee injection recipients prior to TKA compared with patients who did not have knee injections. We specifically assessed (1) timing of HA and CS prior to TKA; (2) type of intra-articular knee injection; as well as (3) associated risk factors. We queried a national database to identify patients who underwent primary TKA from September 2015 to October 2020 (n = 1.5 million). Patients with prior knee injections were stratified to five cohorts: HA within 4 weeks (n = 140), HA 4 to 6 weeks prior (n = 337), CS within 4 weeks (n = 2,344), CS 4 to 6 weeks (n = 2,422), and a no injection, control, cohort prior to TKA (n = 5,000). Bivariate chi-square analyses of outcomes were conducted, and multivariate regressions were used to adjust for comorbidities and assess associated risk factors. The adjusted analysis showed a significant risk in infection for patients receiving an injection within 4 weeks of TKA (p < 0.023) and showed no difference in type of injection (p > 0.050). Additionally, SSIs were increased 1.58 times in the CS within 4 weeks of TKA cohort (p = 0.023). However, no difference in MUA risk was shown at 90-day postoperative (p > 0.212). Furthermore, tobacco use was identified as a risk factor that further increased likelihood of PJI. Intra-articular knee injection less than 4 weeks before TKA increased the risk for PJI; however, past 4 weeks did not confer infection risk. Tobacco use was identified as an associated risk factor that further increased likelihood for PJI. These results highlight the need for surgeons to wait 4 weeks between knee injection and TKA to decrease risk of septic revision.

Abstract
Mechanical knee symptoms secondary to knee osteoarthritis (OA) may warrant knee arthroscopy (KA). Degenerative changes may progress and require a subsequent total knee arthroplasty (TKA). Recent studies have evaluated the timing of KA prior to TKA, associated a narrow interval with increased post-TKA complications. However, an updated analysis is required. We compared surgical outcomes in recipients of KA prior to TKA as stratified by four, time-dependent cohorts (< 12, 12 to 16, 16 to 20, and 20 to 24 weeks prior to TKA). We specifically compared: 90-day (1) manipulations under anesthesia (MUAs); (2) septic revisions at 90 days, 1 year, and 2 years; as well as (3) how various independent risk factors influenced the manipulations or revisions. We queried a national database for patients undergoing TKA. Patients who underwent KA with the following intervals: < 12 (n = 1,023), 12 to 16 (n = 816), 16 to 20 (n = 1,957), and 20 to 24 weeks (1,727) prior to TKA were compared with those patients who did not have a history of KA (n = 5,000). Bivariate analyses were utilized to assess 90 days through 2 years surgical outcomes. Afterwards, multivariate regression models were utilized to assess for independent risk factors. The unadjusted analyses showed an increase in MUA through 2 years among all the KA recipients (p < 0.001). Septic revisions and surgical site infections at all time points were not associated with any of the four arthroscopy time intervals (p > 0.476). The adjusted analyses showed an increased risk for 90-day MUA among all TKA cohorts (p < 0.001). Risk for septic revisions did not reach significance. Delaying TKA by 24 weeks in KA recipients was not associated with a decreased risk in septic revisions. However, there was an apparent risk of MUA at 90 days for all KA cohorts suggesting that waiting after KA before TKA makes no difference in MUA rates. These results update existing literature, may serve as an adjunct to current practice guidelines, and can contribute to shared decision making in the preoperative setting.

Abstract
Dressings for total knee arthroplasty (TKA) typically focus on promoting optimal healing, while preventing infection, allowing for functionality and immediate ambulation, while providing for excellent cosmesis. We have previously described four aspects of closure after TKA involving the: (1) deep fascial layer; (2) subdermal layer; (3) intradermal layer, including the subcuticular region; and (4) a specific aseptic dressing. In this meta-analysis and systematic review of the literature, we will focus on the dressing. Specifically, we assessed: (1) infection risk of different techniques; (2) re-operation or readmission risk; and (3) length of time until dressing change needed. There were 16 reports on infection risk, re-operation risk, and length of time until change needed. A meta-analysis focused on the qualifying wound complication risk reports was also performed. The meta-analysis including four studies (732 patients) demonstrated overall lower wound complication risk with the use of adhesives and mesh dressings (odds ratio 0.67) versus traditional closures. Additionally, studies demonstrated fewer re-operations and readmissions with the use of adhesives and mesh dressings. Furthermore, one report demonstrated mesh dressings persist longer than silver dressings. Therefore, multiple recent reports suggest superior outcomes when using adhesive and mesh dressings for TKAs.

Abstract
INTRODUCTION Isolated medial knee osteoarthritis can be surgically treated with either unicompartmental knee arthroplasty (UKA) or high tibial osteotomy (HTO). Proponents of UKA suggest superior survivorship, while HTO offers theoretically improved alignment and joint preservation delaying total knee arthroplasty (TKA). Therefore, we compared complications in a large population of patients undergoing UKAs or HTOs. We specifically assessed 90 days, 1 year, and 2 years: (1) periprosthetic joint infection (PJI) rates, (2) conversion to TKA rates, as well as (3) complication rates. METHODS A review of an administrative claims database was used to identify patients undergoing primary UKA (n = 13,674) or HTO (n = 1,096) from January 1, 2010 to December 31, 2019. Complication rates at 90 days, 1 year, and 2 years were compared between groups using unadjusted odds ratios (ORs) with 95% confidence intervals. Subsequently, multivariate logistic regressions were performed for PJI and conversion to TKA rates. RESULTS At all time points, patients who underwent UKA were associated with lower rates of infection compared with those who underwent HTOs (all OR ≤ 0.51, all p ≤ 0.010). After 1 year, patients who received UKAs were found to have lower risk of requiring a conversion to a TKA versus those who received HTOs (all OR ≤ 0.55, all p < 0.001). Complications such as dislocations, periprosthetic fractures, and surgical site infections were found at lower odds in UKA compared with HTO patients. CONCLUSION This study provides large-scale analyses demonstrating that UKA is associated with lower infection rates and fewer conversions to TKA compared with patients who have undergone HTO. Dislocations, periprosthetic fractures, and surgical site infections were also found to be lower among UKA patients. However, with careful patient selection, good results and preservation of the native knee are achieved with HTOs. Therefore, UKA versus HTO may be an important discussion to have with patients in an effort to lower the incidence of postoperative infections and complications.

Abstract
Poor metaphyseal fixation secondary to bone loss in revision total knee arthroplasty (TKA) continues to be challenging. One technique to increase implant stability is the use of novel three-dimensional (3D) printed titanium metaphyseal cones with adjunctive stems for added fixation. However, the survival of these novel constructs is poorly understood. Therefore, we sought to examine 3D-printed titanium metaphyseal cone components in revision TKA for aseptic as well as septic reasons and aimed to evaluate: (1) revision-free survivorships; (2) patient-reported outcomes measures (PROMs); (3) postoperative medical complications; and (4) radiographic outcomes. A consecutive series of 62 patients who underwent revision TKA with use of a titanium metaphyseal cone at a single institution between September 1, 2015 and May 31, 2021 were examined. The patients had a minimum follow-up period of 2 years (mean, 40 months, range, 24-72 months). PROMS included Knee Injury and Osteoarthritis Outcome Score Joint Replacement (KOOS-JR) scores at baseline and last clinical follow-up. Overall, when excluding infections, the combined implant survivorship was 96% (52 out of 54), while it was 95% (35 out of 57) for aseptic revisions and 100% (17 out of 17) for septic revisions. Reasons for revisions within the aseptic revision cohort included loosening (5%) as well as periprosthetic joint infections (PJIs) (7.5%). All failures following an index septic revision were due to PJI. Mean KOOS scores at baseline as well as at final follow-up was 43 points (range, 16-80) and 70 points (range, 34-100), respectively. None of the patients had medical complications. Other than the loosening reported (only femoral component), of the surviving patients no patients had evidence of progressive radiolucencies. The use of titanium cones in revision TKA provides good revision-free survivorship at 2 years. Further research is warranted on the longer-term survivorship of 3D-printed titanium cones. The current study has found that 3D-printed titanium cones can be incorporated as part of the revision knee surgeon's armamentarium.

Abstract
Various assessment tools are often used to predict perioperative morbidity among patients older than 75 years who undergo total joint arthroplasty. Yet, few studies describe the use of phenotypic frailty as a predictor for outcomes. The goal of this study was to assess phenotypic frailty with the Sinai Abbreviated Geriatric Evaluation (SAGE) and compare its utility with established assessment tools used in practice. We specifically asked: (1) Can SAGE predict 30-day outcomes, including postoperative delirium? (2) Can SAGE determine the risk of prolonged hospital length of stay? (3) Is SAGE predictive for 30-day readmissions? (4) Can SAGE determine the risk of discharge to a specialized facility? Patients undergoing total hip arthroplasty and total knee arthroplasty were evaluated with the American Association of Anesthesiologists Physical Status (ASA), Charlson Comorbidity Index (CCI), 5-point Modified Frailty Score (5-FS), and SAGE. Assessment scores were determined for each patient, and every incremental change in score was used to predict the likelihood of perioperative complications. A receiver operating characteristic analysis was also performed to calculate testing sensitivity for each assessment tool. The SAGE scores were more likely to predict 30-day complications (odds ratio [95 CI], 2.21 [1.32-3.70]), postoperative delirium (6.40 [1.78-23.03]), and length of stay greater than 2 days (3.90 [1.00-15.7]) compared with ASA, CCI, and 5-FS values. The SAGE scores were not predictive of readmission (1.77 [0.66-4.72]) or discharge to a specialized facility (1.48 [0.80-2.75]). The SAGE score was a more sensitive predictor (area under the curve, 0.700) for perioperative morbidity compared with ASA (0.638), CCI (0.662), and 5-FS (0.644) values. Therefore, SAGE scores can reliably assess risk of perioperative morbidity and may have better clinical utility than ASA, CCI, and 5-FS values for patients undergoing total joint arthroplasty.

Abstract
BACKGROUND Platelet-rich plasma (PRP) usage in orthopedics continues to rise, despite guidelines suggesting non-superiority to comparative cohorts. Therefore, we performed a systematic review and meta-analysis on PRP efficacy using two clinical assessments: (1) Visual Analog Scale and (2) Western Ontario and McMaster Universities Osteoarthritis Index. We assessed consistency and clinical relevancy by determining study heterogeneity (eg, sample sizes, ages, body mass index, arthritic severities, etc.). Comparative cohorts were: (A) hyaluronic acid (HA); (B) corticosteroid (CS); (C) normal saline (NS); and (D) exercise therapy. We performed sub-analyses of structural changes assessed on ultrasound, radiograph, or magnetic resonance imaging . METHODS We utilized PubMed, Cochrane Library, and Embase databases up to December 1, 2021, according to Preferred Reporting Items for Systematic-Reviews and Meta-Analyses guidelines. Twenty-four studies met criteria, with comparisons to: HA (n = 11); CS (n = 6); NS (n = 5); and exercise therapy (n = 3). Seven studies assessed structural changes. Evaluations utilized a methodological scoring system. I2 statistics and forest plots pooled analyses and delineated study results. RESULTS PRP led to Visual Analog Scale and Western Ontario and McMaster Universities Osteoarthritis Index improvements in most studies when compared to HA, CS, and NS (P ≤ .05). Comparison to exercise therapy resulted in inconclusive findings (P ≥ .05). However, substantial heterogeneity (I2 ≥ 76%) was reported due to study variability. No differences were found when assessing structural changes or cartilage thickness by magnetic resonance imaging (standardized mean difference -0.01 [-0.19, 0.18], P = .91). CONCLUSIONS PRP may be associated with pain and functional improvements but was not clinically relevant (inconsistent study- and patient-metrics). In addition, PRP did not confer superiority when assessing knee-related structural changes.

Abstract
INTRODUCTION Revision total hip arthroplasty (THA) can be challenging in the face of proximal femoral bone loss, catastrophic implant failure, or recurrent hip instability. Tapered modular femoral stems have shown substantial success at short follow up for aseptic revisions. The purpose of this study was to report mid-term revision THA outcomes of a tapered modular femoral stem at a tertiary referral center used to treat both aseptic as well as periprosthetic joint infections (PJIs). We specifically sought to assess: (1) revision-free implant survivorship; (2) patient-reported outcome measurements (i.e., Hip Disability and Osteoarthritis Outcome Score, Joint Replacement [HOOS JR]); (3) postoperative surgical complications and 30-day readmissions; as well as (4) radiographic outcomes. MATERIALS AND METHODS We reviewed a consecutive series of 92 patients who underwent revision THA between 2009 and 2013 with a tapered modular femoral stem. After accounting for mortality (n=7) and loss to follow up (n=13), a total of 72 implants in 66 patients who had eight years of mean follow up (range, 2 to 11) were included. PJI (46%) was the predominant preoperative indication for revision THA, followed by aseptic loosening (25%), periprosthetic fracture (18%), and symptomatic hardware (10%). Outcomes of interest included all-cause revision-free survivorship, postoperative complications, and HOOS JR, as well as SF-12 scores. Radiographically, they were evaluated for subsidence, radiolucencies, and loosening. RESULTS Aseptic revision-free survivorship of the femoral component was 95.8% (69 out of 72). Including septic cases, revision-free survivorship was 87.5% (63 cases), and 60 implants (83.3%) had an all-cause revision-free survivorship. For those patients who underwent septic revisions, eight out of nine remained infection free, while one underwent a resection arthroplasty. Furthermore, the cause for femoral aseptic revisions were subsidence (1.4%) and aseptic loosening (2.8%). Functional score improvements for HOOS JR, SF-12 PCS, as well as MCS were 29, 13, and 2, respectively (all p<0.001). There were eight emergency department visits (11.1%,) and six inpatient readmissions (8.3%). Additionally, two patients had dislocations (2.8%, two out of 72) not requiring revision. There were two cases of femoral subsidence and one aseptic loosening requiring revision; whereas, the rest did not demonstrate any progressive radiographic lucencies. DISCUSSION The eight-year mean survivorship results of the tapered modular femoral stems in revision THA demonstrated excellent results. Our series found improved outcome scores and relatively low postoperative complications, which indicate a favorable implant survivorship profile for revision THA. CONCLUSION These results serve to inform arthroplasty surgeons of expected outcomes of the modular stems when used for patients who need complex revision THA.

Abstract
Conversion total knee arthroplasty (TKA) is suggested to incur similar complication rates to revision arthroplasties. However, current billing codes do not allow for the differentiation between this operation and primary TKAs. Therefore, the purpose of this study was to compare outcomes of these two surgeries, as well as revision TKAs. Specifically, we analyzed (1) medical complications, (2) surgical complications, and (3) revision rates at 90 days and 1 year. We queried a national, all-payer database to identify patients who underwent TKA without prior implants (n = 1,358,767), required conversion TKA (n = 15,378), and who underwent revision TKA (n = 33,966) between January 1, 2010, and April 30, 2020. Conversion TKA patients (prior implant removal) were identified using the Current Procedural Terminology (CPT) codes. Outcomes studied included 30-day readmission rates and 90-day, as well as 1-year, medical and surgical complications. Conversion TKAs had greater 30-day readmission rates and incidences of most of the complications studied when compared with primary TKAs. The majority of outcomes when comparing between primary, conversion, and revision TKAs were significantly different (p < 0.01). In contrast, conversion TKA complications were similar to revision TKA. Conversion TKAs have higher postoperative complications than primary TKAs and share more similarities with revision TKAs. Thus, the lack of billing codes differentiating conversion and primary TKAs creates a challenge for orthopaedic surgeons.

Abstract
CASE A 56-year-old woman underwent a left total hip arthroplasty (THA) after developing avascular necrosis after chemotherapeutic treatment of breast cancer. She presented approximately 2 years after index THA with left groin pain and complaints of instability. Imaging revealed pseudodislocation of the ceramic femoral head with erosion through the acetabular component. Intraoperative evaluation revealed a dissociated polyethylene liner, damaged acetabular locking mechanism, metallosis, and well-fixed and aligned components. Treatment consisted of component retention, bone grafting, and dual-mobility liner cementation into the acetabular component. CONCLUSIONS The two-year follow-up demonstrated a pain-free, well-functioning hip, bone graft incorporation, and no evidence of loosening.

Abstract
BACKGROUND Characterizations and factors influencing longer term performance of second-generation sequentially irradiated and annealed highly cross-linked polyethylene (HXLPE) are lacking. We evaluated patients who underwent total hip arthroplasty with HXLPE at mean 10-year follow-up for (1) linear and volumetric wear rates, (2) patient and implant characteristics, (3) implant survivorships, and (4) functional scores. METHODS We evaluated 130 hips (110 patients) that received HXLPE acetabular liners at a single center. The mean age was 56 years (range, 20-79 years), with a mean follow-up of 10 years (range, 8-15). Radiographic linear (millimeters/year) and volumetric (cubic millimeters/year) wear rates were quantified using radiographic analysis. Survivorship was assessed by all-cause and wear-related revision rates. Functional outcomes were assessed by Short Form 12 and modified Harris Hip Scores. RESULTS The mean linear wear rate was 0.02 ± 0.03 mm/y, and the mean volumetric wear rate was 12.6 ± 5.3 mm3/y. Younger age had higher volumetric wear (total and yearly, P = .01). Increasing body mass index trended toward higher total and yearly linear (both, P ≤ .09) and volumetric wear (both, P ≤ .07). Ten patients required revisions, with an all-cause survivorship of 92% and a wear survivorship of 100%. The mean modified Harris Hip Scores was 84, and the mean Short Form 12 scores were 46 (physical) and 55 (mental). CONCLUSION We observed low linear and volumetric wear rates for HXLPE at 10-year mean follow-up. Younger age and higher body mass index at the time of surgery may be important patient characteristics influencing long-term wear. These results illustrate the potential for this second-generation HXLPE to be an appropriate long-term total hip arthroplasty interface.

Abstract
BACKGROUND Social determinants of health (SDOH) may play a larger role in predicting patient outcomes as outpatient total hip arthroplasty (THA) expands. We specifically examined the association between SDOH and patient metrics (demographics and comorbidities) for: (1) 30-day post-discharge costs of care; (2) lengths of stay (LOS); and (3) patient-reported outcomes (Hip Disability and Osteoarthritis Outcomes Score for Joints Replacement (HOOS JR)). METHODS Medicare patients who underwent primary THA between 2018 and 2019 were identified. Those who had complete social determinant data were included (n = 136). Data elements were drawn from institutional, regional, and government databases, as well as the Social Vulnerability Index (SVI). Multiple regression analyses were performed to determine SDOH and baseline comorbidities associations with costs, LOS, and HOOS JR scores. RESULTS Various SDOH factors were associated with higher 30-day costs, including residing in a food desert ($53,695 ± 15,485; P < .001) and the following SVI themes: 'Minority Status and Language' ($24,075 ± 9845; P = .01) and 'Housing and Transportation' ($16,190 ± 8501; P = .06), although the latter did not meet statistical significance. Baseline depression was associated with longer LOS (P = .02), while none of the other SDOH or patient metrics affected LOS. No relationships were observed between SDOH and HOOS JR changes from baseline. CONCLUSION Patients who live in food deserts and have minority status had higher costs of care after primary THA. Poor housing and transportation may also increase costs, albeit insignificantly. These results highlight the utility of assessing SDOH-related risk factors to optimize post-operative outcomes, with potential implications for bundled care.

Abstract
BACKGROUND Low socioeconomic status and neighborhood context has been linked to poor health care outcomes after total knee arthroplasty (TKA). The area deprivation index (ADI) addresses this relationship by ranking neighborhoods by socioeconomic disadvantage. We examined the following relationships of the ADI among TKA recipients: (1) patient demographics, (2) lengths of stay (LOS), (3) nonhome discharges, and (4) 90-day readmissions, emergency department visits, and reoperations. METHODS We reviewed a consecutive series of primary TKAs from 2018 through 2020 at a tertiary health care system. A total of 3928 patients who had complete ADI data were included. A plurality of patients (14.9%) were categorized within ADI 31-40, below the national median ADI of 47. Associations between the national ADI decile and 90-day postoperative health care utilization metrics were evaluated using multivariate regressions (adjusted for patient demographics and comorbidities). RESULTS The 91-100 ADI cohort was disproportionately African American, female, younger, and smokers. Compared with ADI 31-40 (reference), the ADI 61-70 cohort was associated with higher odds of LOS ≥3 days (odds ratio [OR] = 1.6 [1.08-2.36], P = .019) and nonhome discharges (OR = 1.73 [1.08-2.75], P = .021). The ADI 91-100 cohort was associated with the highest odds of prolonged LOS (OR = 2.27; [1.47-3.49], P < .001), nonhome discharges (OR = 3.49 [2.11-5.78], P < .001), and all-cause readmissions (OR: 1.79, [1.02-3.14], P = .044). No significant associations were found between the ADI and 90-day emergency department visits or reoperations (P > .05). CONCLUSION A higher ADI was associated with prolonged LOS, nonhome discharge status, and 90-day readmissions after TKA. This index highlights potential areas of intervention for assessing health care outcomes.

Abstract
The use of the distal femoral replacement (DFR) has grown in recent years. Historically, this procedure was reserved for malignancy and complex revision cases with relative success. In recent years, complex reconstruction cases have had relative success. DFR has been associated with a range of complications including anterior knee pain, patellar instability, limitations in knee motion, and rotational instability that are sequelae of altered patello-femoral mechanics. Thus, subsequent dysfunction may require revision. To our knowledge, no surgical technique to correct DFR patello-femoral maltracking has been demonstrated in current literature. We present a surgical technique for DFR patello-femoral maltracking corrected surgically with femoral component revision and femoral stem retention.

Abstract
Background Knee osteoarthritis (OA) is a widespread and debilitating disease that continues to plague patients. Over the past decade, neuromuscular electrical stimulation (NMES) therapy has shown promise in alleviating knee OA-related symptoms. This study sought to evaluate the efficacy and safety of a home-based NMES therapy for reduction of pain, stiffness, and function associated with knee OA. Material and methods A randomized, sham-controlled, double-blind, multicenter trial was conducted with 12-week follow-up in 156 knee OA patients receiving either home-based NMES therapy or a modified low-voltage NMES therapy. Outcome measures including knee pain, stiffness, and functionality were collected at baseline through week 12 after the therapy. The primary endpoint was the percentage change from baseline (PCFB) in the Visual Analog Scale (VAS) pain for a patient-nominated physical activity. Secondary endpoints included VAS for general knee pain, Western Ontario and McMaster Universities Osteoarthritis Index, Knee Injury and Osteoarthritis Outcome Score Joint Replacement, and isometric quadriceps strength test. Results A clinically meaningful reduction for VAS Nominated Activity was higher in the per-protocol treatment-compliant NMES group than that in the sham low-voltage NMES group at week 12 (PCFB of 42.8% vs 38.6%, P = .562). This was similarly true for the Western Ontario and McMaster Universities Osteoarthritis Index pain subscale (PCFBs of 36.8% vs 26.6%, P = .038). Similar trends and reductions of pain were observed for VAS General, Knee Injury and Osteoarthritis Outcome Score Joint Replacement Pain subscale, and isometric quadriceps strength. Conclusion Home-based NMES treatment resulted in a clinically meaningful reduction of knee pain, stiffness, and knee functional improvements at week 12 compared with sham NMES treatment.

Abstract
BACKGROUND Traditional management of prosthetic joint infection following total knee arthroplasty (TKA) consists of a 2-stage approach. However, 1.5-stage exchange has seen preliminary success, whereby metal femoral and all-polyethylene tibia components are placed without intention for subsequent second stage. We sought to examine all patients who underwent a 1.5-stage exchange TKA at a single institution compared to historical 2-stage controls. We assessed the following: (1) infection-free survivorship and risk factors for reinfection; (2) 1-year surgical/medical outcomes; (3) patient-reported outcomes (ie, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement [KOOS JR]); and (4) radiographic outcomes. METHODS We reviewed all patients undergoing a 1.5-stage (between 2015 and 2019) and 2-stage exchange TKA (between 2011 and 2016) at a single institution. A total of 162 knees were included (1.5-stage: 114; 2-stage: 48) with mean clinical follow-up of 2.6 years. KOOS JR scores and radiographic outcomes were evaluated at last clinical follow-up. RESULTS The 1.5-stage exchange TKA resulted in a 10.1% difference in infection-free survival (85.1% vs 75.0%, P = .158), compared to 2-stage exchange. Prior prosthetic joint infection was found to be an independent risk factor for reinfection (P = .030). Overall, postoperative complications were lower among 1.5-stage exchanges (8.8% vs 31.3%, P < .001). KOOS JR scores improved more from baseline among 1.5-staged (Δ24.7 vs Δ16.6, P < .001). Radiographic review did not demonstrate any progressive radiolucent lines, subsidences, or failures in either group. CONCLUSION A 1.5-stage exchange TKA is an effective alternative to the traditional 2-stage protocols with noninferior infection eradication and absence of radiographic complications at over 2 years of mean follow-up.

Abstract
Background: Various methods exist for managing the joint capsule during the Latarjet procedure. Repairing the capsule to the native glenoid rim results in an extra-articular bone block, while repairing it to the remnant coracoacromial ligament stump of the coracoid graft renders it intra-articular. The technique that optimizes patient outcomes is not well defined. Purpose: To compare the outcomes of intra-articular and extra-articular bone block techniques for the Latarjet procedure. Study Design: Systematic review; Level of evidence, 4. Methods: Using PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines, we queried the PubMed, EMBASE, and the Cochrane Library for all studies reporting outcomes of the Latarjet procedure with a clearly defined method of capsular repair that rendered the coracoid graft intra-articular or extra-articular. The included levels of evidence and degree of heterogeneity in this study precluded meta-analysis. Outcomes of interest included preoperative variables, surgical technique, rehabilitation protocols, functional outcome assessments, recurrent instability, range of motion, and radiographic findings. Results: A total of 16 studies including 816 patients were included. A total of 8 studies employed an intra-articular bone block in 338 patients, while the other 8 employed an extra-articular technique in 478 patients. There was variation among studies in reference to baseline patient characteristics, surgical techniques, rehabilitation, methods for assessing patient outcomes, and follow-up times. Rates of postoperative instability were reported in 8 intra-articular (0%, 0%, 2.1%, 2.7%, 3.2%, 5%, 5.4%, 5.9%) and 7 extra-articular (0%, 0%, 1.2%, 2%, 3.9%, 6.3%, 14%) bone block studies. Postoperative osteoarthritis or progression of preoperative osteoarthritis was reported in 5 intra-articular bone block studies (0%, 5.6%, 23.5%, 23.5%, 25%) and 4 extra-articular bone block studies (0%, 1.9%, 5.2%, 8.6%). Conclusion: Varying capsular repair methods appeared to provide similar outcomes regarding stability. There was an apparent trend toward higher rates of post-traumatic arthritis among studies in which an intra-articular bone block technique was employed; however, it is possible that this was influenced by substantially different follow-up times between groups and other various sources of heterogeneity among the included studies. There were no studies in the literature directly comparing intra-articular and extra-articular bone block techniques. Large-scale randomized controlled trials or comparative studies are needed to draw stronger conclusions comparing the 2 techniques.

Abstract
BACKGROUND Clostridioides difficile infection (CDI) may be a surrogate for poor patient health. As such, a history of CDI before THA may be used to identify patients at higher risk for postoperative CDI and complications after THA. Investigations into the associations between CDI before THA and postoperative CDI and complications are lacking. QUESTIONS/PURPOSES We compared the (1) frequency and potential risk factors for CDI after THA, (2) the frequency of 90-day complications after THA in patients with and without a history of CDI, and (3) the length of stay and frequency of readmissions in patients experiencing CDIs more than 6 months before THA, patients experiencing CDIs in the 6 months before THA, and patients without a history of CDI. METHODS Patients undergoing primary THA from 2010 to 2019 were identified in the PearlDiver database using ICD and Current Procedural Terminology codes (n = 714,185). This analysis included Medicare, Medicaid, and private insurance claims across the United States with the ability to perform longitudinal and costs analysis using large patient samples to improve generalizability and reduce error rates. Patients with a history of CDI before THA (n = 5196) were stratified into two groups: those with CDIs that occurred more than 6 months before THA (n = 4003, median 2.2 years [interquartile range 1.2 to 3.6]) and those experiencing CDIs within the 6 months before THA (n = 1193). These patients were compared with the remaining 708,989 patients without a history of CDI before THA. Multivariable logistic regression was used to evaluate the association of risk factors and incidence of 90-day postoperative CDI in patients with a history of CDI. Variables such as antibiotic use, proton pump inhibitor use, chemotherapy, and inflammatory bowel disease were included in the models. Chi-square and unadjusted odds ratios with 95% confidence intervals were used to compare complication frequencies. A Bonferroni correction adjusted the p value significance threshold to < 0.003. RESULTS Prior CDI during either timespan was associated with higher unadjusted odds for postoperative CDI (CDI > 6 months before THA: OR 8.44 [95% CI 6.95 to 10.14]; p < 0.001; CDI ≤ 6 months before THA: OR 49.92 [95% CI 42.26 to 58.54]; p < 0.001). None of the risk factors included in the regression were associated with increased odds for postoperative CDI in patients with preoperative history of CDI. Patients with a history of CDI before THA were associated with higher unadjusted odds for every 90-day complication compared with patients without a history of CDI before THA. CDI during either timespan was associated with longer lengths of stay (no CDI before THA: 3.8 days; CDI > 6 months before THA: 4.5 days; CDI ≤ 6 months before THA: 5.3 days; p < 0.001) and 90-day readmissions (CDI > 6 months before THA: OR 2.21 [95% CI 1.98 to 2.47]; p < 0.001; CDI ≤ 6 months before THA: OR 3.39 [95% CI 2.85 to 4.02]; p < 0.001). CONCLUSION Having CDI before THA was associated with higher odds of postoperative CDI compared with patients without a history of CDI. A history of CDI within the 6 months before THA was associated with the greatest odds for postoperative complications and readmissions. Providers should strongly consider delaying THA until 6 months after CDI, if possible, to provide adequate time for patient recovery and eradication of infection. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
BACKGROUND Renal transplants are the most commonly performed solid-organ transplants worldwide. It is unclear whether a kidney transplant is associated with reduced postoperative complications in comparison with patients on dialysis for end-stage renal disease (ESRD). The purpose of this study was to utilize a national database to compare readmissions, complications, and costs associated with primary total hip arthroplasty (THA) between matched renal transplant recipients (RTRs) and patients on dialysis for ESRD. METHODS Patients with a renal transplant (N = 1,401) and those on dialysis for ESRD (without a transplant) (N = 1,463) prior to being treated with a THA from 2010 to 2019 were identified within the PearlDiver database. RTRs and patients on renal dialysis were frequency-matched 1:1 on the basis of 9 patient characteristics, resulting in 582 patients in each group. Length of hospital stay, readmissions, complication rates up to 2 years, and total costs up to 1 year were compared between the groups using chi-square and multivariable logistic regression analyses to calculate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Patients on renal dialysis had an increased mean length of stay (6.3 days) compared with RTRs (4.6 days, p < 0.01). After adjusting for age, tobacco use, and diabetes, patients on renal dialysis were more likely to be readmitted by 90 days (OR = 1.59; CI = 1.11 to 2.29, p < 0.01) and have mechanical complications (OR = 2.13; CI = 1.08 to 4.45, p = 0.03) and revisions (OR = 2.14; CI = 1.14 to 4.01, p = 0.01) by 2 years. Patients on renal dialysis were also more likely to have periprosthetic joint infections at 1 year (OR = 1.91; CI = 1.02 to 3.71, p = 0.04). Patients on dialysis incurred 14% higher costs at 1 year (p = 0.11). CONCLUSIONS Patients on renal dialysis had more readmissions, complications, and costs after THA when compared with RTRs. Specifically, patients on renal dialysis were more likely to have longer index lengths of stay, more readmissions by 90 days, and more mechanical complications and revision surgery by 2 years. Patients on dialysis also incurred higher costs and had greater odds of PJI. These results suggest that joint surgeons may consider delaying THA in suitable patients until after renal transplantation to reduce postoperative complications and costs.
